| Protection
circuit functions |
- 1. Overcharge protection
- Stops charging when the voltage exceeds the specified
maximum value in order to prevent the battery from overheating
or exploding due to overcharging.
- 2. Overdischarge protection
- Stops discharging when the voltage falls below the specified
minimum value in order to prevent degradation of the battery
due to overdischarging.
- 3. Overcurrent protection
- Stops discharging when an abnormal current (several amps
or more) flows in the battery due to a fault in the device.
- 4. Short-circuit protection
- Promptly stops discharging when a large current of several
tens of amps flows due to external shorting of the battery
pack (etc.).
